I reviewed and compared four window companies and Window Source of Rhode was best by far. Window source of R.I. excels in quality, value, and workmanship. The windows I purchased are comparable to the so called higher end windows but at a cost that fit my budget. The workmanship was fantastic. Richard the owner of window source came by and personally measured each window to ensure proper fit. Bobby and Harry were expert installers and I could not be happier with their workmanship. The installation included exterior aluminum wraps I purchased separately for extra protection and a clean, neat look. . The windows offered by window source of R.I. are already making a huge difference in my fuel costs with the elimination of unwanted drafts. So for outstanding quality, value, and workmanship on your window replacements look no further than Window Source of R.I.
